Finally told me about his ex

He just talked to me a little bit about his ex. This seems really big right now since before he wouldn't even mention her. They were apparently together for a year and half,broke up August of 2015. I don't think he's completely over her even though it's been a little while. But I think he still loves her... she's beautiful, couldn't help but feel inferior. But does it mean somehting that he talked about her with me?
